Frostbanger Auto F4Sundae Thumper
Creamy dessert gas, fresh spice and heavy frost in a fast, colour-rich auto.
Sundae Frost Auto by Fast Buds is an F1 hybrid feminized autoflower bred from Frostbanger Auto F4 x Sundae Thumper, combining cup-proven auto genetics with dessert-gas flavour and standout resin coverage. The profile is sweet, fresh and slightly spicy, with creamy dessert notes layered over a deeper, heavier edge that gives the strain more weight than a simple fruit-led auto.
With balanced 50% sativa / 50% indica genetics, Sundae Frost Auto stays compact and efficient at around 60-100 cm, making it a practical choice for smaller spaces and quick production cycles. The full lifecycle runs around 70-75 days, with indoor yields of 450-600 g/m2 and outdoor potential of 3-9 oz/plant. During testing, Fast Buds observed two main colour expressions: one with green buds and subtle purple or pink accents, and another with green buds, purple highlights and dark, blackish foliage. Both phenotypes share the same sweet-spicy aromatic profile, heavy frost and strong visual appeal.
